"Bel Ami," filming for which is slated to begin next month in Paris, is an adaptation of an 1885 Guy de Maupassant short story and stars Pattinson as young journalist George Duroy, who rises from rags to riches by seducing Paris' influential society women. Ricci will play Clotilde de Marelle, the wife of an oft-away railway inspector who strikes up a relationship with Duroy. The film also stars Thurman as Clotilde's friend Madeleine Forestier, a onetime friend and mentor who becomes Duroy's lover, and Kristin Scott Thomas as another of Duroy's socialite paramours.
